Spark Race Category

1, size: according to thread size, thread length and hexagonal comparison classification, like the model with DK LD DM (M12 × 1.25), their threads than other general and professional spark plug to fine (M12 × 1.25).

2, calorific value: popular point that is the size of the spark plug heat capacity, which is related to the requirements of the engine. The general engine requires a spark plug between 6 and 7, with a turbocharged engine on the need 8. The greater the power, the need for greater heat dissipation, and vice versa. But when the heat value is too high will make the insulator below the ignition side, will make the top carbon deposition, affecting the ignition. When the calorific value is too low, it is easy to melt the electrode and damage the engine.

3, whether the resistance: the current domestic car engine fuel injection are many using EFI, so the original spark plugs are with resistance. The main role of resistance is to shield and suppress the impact of electromagnetic waves on the spark plug.

4, electrode classification: from the material that is divided into nickel copper (ordinary), platinum and iridium. Which iridium platinum represents the center electrode is platinum and the electrode is platinum. Compared to other common materials, iridium platinum performance: 1, start performance better, because the need to start the lower the voltage, the easier to start (iridium need the lowest voltage, followed by platinum, the highest general). 2, the higher the melting point, the longer life. The iridium has a melting point of 2454 °, a platinum of 1769 ° and a nickel copper of 1453 °. 3, cutting-edge discharge, will burn more fully, more power, the ignition side is not easy to carbon deposition. 5, the gap: the size of the gap will affect the ignition end of the flame core size. The larger the gap, the bigger the flame, and vice versa. This is required to adjust in accordance with the requirements of the engine, if the gap is too large, will cause the ignition system needs to increase the voltage, may lead to fire, fuel economy and damage to the ignition system. If the gap is too small, it will cause the phenomenon of not flashing (sales to remind the repair master before the installation, you must observe whether there is contact between the electrodes, because the logistics or other conditions caused by bumps caused by falling on the ground so that two motors stick Together).

Fit Model

Assembly production

1, through the automatic powder machine, the amount of resistance powder (with Bosch the same supplier) + center electrode + screw + expansion powder into the finished ceramic insulator inside, after heating, the internal structure of the spark plug has been formed.

2, after forming the need for internal voltage test, after 25000V high voltage on each of the detection of whether the breakdown of insulation and leakage, excluding unqualified products.

3, through the hot-pressing assembly line, the insulator and iron shell welding. And we are using hot riveting welding technology, this technology is currently Bosch's spark plug is also being used. Because the welding is the need for heating, so in the hexagonal screw will be under a circle of light blue halo. The NGK is the use of cold riveting technology, so the insulator and iron shell where there will be a small layer of pale white powder.

4, after assembly into the finished product, will be simulated air pressure detection, simulation of the engine cylinder operating pressure, the finished product installed into the test center electrode and the distance between the side of the electrode to achieve the ignition requirements of the engine to detect its performance and quality.

5, the detection of quality problems of finished products, for packaging.
